参照图 1， 示出了根据本发明实施例一的一种视频交互方法的步骤流程图， 包括 以下步骤 S102至步骤 S106: 步骤 S102: 中转服务器获取移动终端的视频通讯状态； 其中， 上述移动终端包括一个视频通话发起方移动终端和多个视频通话接收方移 动终端。 上述视频通讯状态包括： 接入状态、 失去连接状态、 通讯状态、 和保持通讯状态。 其中， 接入状态设置为指示移动终端接入中转服务器并进行初始化过程； 失去连接状 态设置为指示移动终端初始化失败或与中转服务器的连接中断； 通讯状态设置为指示 视频通话发起方移动终端与中转服务器连接正常； 保持通讯状态设置为指示视频通话 接收方移动终端与中转服务器连接正常。 本步骤中， 中转服务器可以通过向各个移动终端发送视频通讯状态查询命令， 查 询各个移动终端的视频通讯状态。 步骤 S104: 中转服务器根据视频通讯状态判断移动终端与中转服务器连接是否正 常； 本步骤中， 中转服务器根据获取的各个移动终端的视频通讯状态， 判断各个移动 终端与中转服务器的连接是否正常。 步骤 S106: 中转服务器在视频通话发起方移动终端与中转服务器连接正常时， 获 取视频通话发起方移动终端的当前视频信息， 并发送给多个视频通话接收方移动终端 中与中转服务器连接正常的移动终端。 本步骤中，当中转服务器判断视频通话发起方移动终端与中转服务器连接正常时， 获取其当前视频信息， 并发送给与中转服务器连接正常的接收方移动终端， 此时， 与 中转服务器连接正常的接收方移动终端可以有多个， 也可能仅有一个。 可能接收方移 动终端均处于保持通讯状态， 也可能有部分仍处于接入状态， 对于接入状态的这部分 接收方移动终端， 当其与中转服务器连接正常后， 即其处于保持通讯状态后， 中转服 务器再向其发送发起方移动终端的视频信息。 而当连接正常的接收方移动终端在连接 过程中与中转服务器连接中断时， 对于这部分接收方移动终端， 则中转服务器停止向 其发送发起方移动终端的视频信息， 直到其再次连接正常。 相关技术中， 只能进行两个移动终端之间的点对点视频通话， 无法实现多个支持 视频通话的移动终端同时进行视频通话。 通过本实施例， 采用设置中转服务器， 通过
中转服务器查询参与视频通话的多个移动终端的视频通讯状态， 根据该视频通讯状态 向与中转服务器连接正常的多个视频通话接收方移动终端发送视频通话发起方移动终 端的当前视频， 解决了现有技术无法实现多个支持视频通话的移动终端同时进行视频 通话的问题， 进而达到了多个支持视频通话的移动终端同时进行视频通话， 扩展移动 终端的功能业务的效果。 优选的， 中转服务器还在视频通话发起方移动终端与中转服务器连接正常时， 获 取多个视频通话接收方移动终端中与中转服务器连接正常的移动终端的当前视频信 息， 并发送给视频通话发起方移动终端。 通过将接收方移动终端的视频信息发送给发 起方移动终端， 实现了发起方和接收方之间的双向交互。 优选的， 中转服务器还获取多个视频通话接收方移动终端中与中转服务器连接正 常的移动终端的当前视频信息， 并发送给除该当前视频信息所属的移动终端外的， 其 它与中转服务器连接正常的视频通话接收方移动终端。 该优选方案中， 中转服务器在 获取接收方移动终端的视频信息时， 有可能视频通话发起方移动终端与中转服务器连 接正常， 也有可能发起方移动终端已经与中转服务器断开连接， 在后一种情况下， 只 要还存在多个与中转服务器连接正常的接收方移动终端， 则这些接收方移动终端之间 仍可进行视频交互。 通过将接收方移动终端的视频信息发送给除本终端外的其它接收 方移动终端， 实现了多个接收方移动终端之间的相互交互。 优选的， 中转服务器还将获取的各个移动终端的视频通讯状态发送给除本移动终 端外的， 其它与中转服务器连接正常的移动终端。 该优选方案中， 中转服务器在发送 移动终端的视频通讯状态信息时， 有可能视频通话发起方移动终端与中转服务器连接 正常， 也有可能发起方移动终端已经与中转服务器断开连接， 在前一种情况下， 中转 服务器可以将各个移动终端的视频通讯状态发送给除本移动终端外的， 其它与中转服 务器连接正常的发送方移动终端和 /或接收方移动终端， 在后一种情况下， 只要还存在 多个与中转服务器连接正常的接收方移动终端， 就不影响视频通讯状态信息的发送。 通过将移动终端的视频通讯状态发送给除本终端外的其它移动终端， 实现了各个移动 终端对其它移动终端状态的获知， 可以进一步根据获知的其它移动终端的状态进行相 应的处理。 优选的， 中转服务器每隔设定时间向各个移动终端发送查询命令， 通过查询获取 各个移动终端的视频通讯状态。优选的，该查询命令为 SIP ( Session Initiation Protocol, 会话初始协议） 的查询命令。 通过查询命令获知移动终端的视频通讯状态， 提高了中 转服务器的状态处理能力， 进而提高了系统的视频交互效率。 而将 SIP的查询命令应
用于中转服务器查询移动终端的状态的过程中，充分利用了 SIP查询命令的结构特点， 减小了系统实现难度， 节约了系统实现成本。 实施例二 参照图 2， 示出了根据本发明实施例二的一种视频交互方法的步骤流程图， 包括 以下步骤 S202至步骤 S206: 步骤 S202: 初始化阶段。 需要进行视频通话的多个移动终端连接中转服务器， 通过本步骤， 各个移动终端 (包括一个视频通话发起方终端和多个视频通话接收方终端） 接入中转服务器。 步骤 S204: 中转服务器查询判断各个接入的移动终端的视频通讯状态， 并且根据 移动终端的视频通讯状态进行相应的操作。 中转服务器会隔一段时间向各个移动终端发送查询命令， 查询各个移动终端的状 态。该查询命令可以由本领域技术人员根据实际情况适当选用适合的现有的消息命令， 或通过对现有的消息命令进行扩展实现， 优选的， 可以选用 SIP的查询命令。 移动终端的视频通讯状态有以下几种： 接入状态、 失去连接状态、 通讯状态、 保 持通讯状态。 其中， 接入状态是指移动终端接入中转服务器， 并且进行初始化过程； 失去连接状态是指移动终端连上中转服务器后， 初始化失败， 或者突然连接中断的过 程； 通讯状态是指， 移动终端与中转服务器通讯正常， 并且当前移动终端为视频通话 的发起方； 保持通讯状态是指， 移动终端和中转服务器通讯正常， 并且当前移动终端 为视频通话的接听方。 在单位时间内， 各个移动终端中， 最多只有一个终端处于通讯 状态， 其余是保持通话状态或接入状态或者失去连接状态。 当中转服务器检测到移动终端的视频通讯状态后， 会将移动终端的状态分发到各 个移动终端。 如果待发送数据的移动终端的当前视频通讯状态为保持通讯， 则中转服 务器会将该移动终端的当前的视频通讯状态和当前移动终端获取的视频信息分发到其 他移动终端， 并且中转服务器会定时更新该移动终端的视频信息和视频通讯状态； 如 果待发送数据的移动终端的当前视频通讯状态为通讯状态， 则中转服务器会将该移动 终端的当前视频通讯状态和视频信息以及语音信息分发到其他移动终端， 并且定时更 新该移动终端的视频通讯状态和视频信息以及语音信息； 如果移动终端的视频通讯状 态为接入状态或失去连接状态， 中转服务器会将该移动终端的当前视频通讯状态分发 到其他移动终端中， 并且定时更新。
中转服务器中的视频通话发起方移动终端和视频通话接收方移动终端的视频通讯 状态转化如图 3和图 4所示。 其中， 图 3是中转服务器中的视频通话发起方移动终端 的状态转化图， 图 4是中转服务器中的视频通话接收方移动终端的状态转化图。 如图 3所示， 视频通话发起方移动终端开始接入中转服务器， 进入接入状态， 若 连接成功， 则对于发起方移动终端， 转为通讯状态， 若连接不成功， 即初始化失败， 则转入失去连接状态。 此外， 在连接成功之后的过程中， 有可能出现移动终端与中转 服务器连接中断的情况， 此时， 发起方移动终端由通讯状态转入失去连接状态。 在发 起方移动终端处于失去连接状态时， 其有可能会尝试再次与中转服务器进行连接， 即 再次进入接入状态， 开始再次连接中转服务器。 而当失去连接状态持续一定时间后， 则流程结束。 对于视频通话接收方移动终端， 如图 4所示， 当其开始接入中转服务器， 进入接 入状态， 若连接成功， 则对于接收方移动终端， 转为保持通讯状态， 若连接不成功， 即初始化失败， 则转入失去连接状态。 此外， 在连接成功之后的过程中， 有可能出现 移动终端与中转服务器连接中断的情况， 此时， 接收方移动终端由保持通讯状态转入 失去连接状态。 在接收方移动终端处于失去连接状态时， 其有可能会尝试再次与中转 服务器进行连接， 即再次进入接入状态， 开始再次连接中转服务器。 而当失去连接状 态持续一定时间后， 则流程结束。 步骤 S206: 视频交互结束。 当所有的移动终端都处于失去连接状态一段时间后， 本次视频交互通讯结束。 通过本实施例， 提供了一个能使多个支持视频通话的移动终端， 同时进行视频通 话的方案， 从而扩展了移动终端的功能业务。 实施例三 参照图 5， 示出了根据本发明实施例三的一种视频交互系统的结构示意图。 本实施例的视频交互系统包括视频通话发起端 502 (即视频通话发起方移动终 端）、 中转服务器 504、 以及多个视频通话接收端 506 (即视频通话接收方移动终端）。 视频通话发起端 502及多个视频通话接收端 506均与中转服务器 504连接， 服务器 504根据各个终端的视频通讯状态， 实现各个终端之间的视频交互。
其中， 中转服务器 504的结构如图 6所示， 包括： 获取模块 5042， 设置为获取各 个移动终端（包括视频通话发起端 502和多个视频通话接收端 506 ) 的视频通讯状态， 其中， 视频通讯状态包括： 接入状态、 失去连接状态、 通讯状态、 和保持通讯状态， 接入状态设置为指示移动终端（包括视频通话发起端 502和多个视频通话接收端 506 ) 接入中转服务器 504并进行初始化过程， 失去连接状态设置为指示移动终端 （包括视 频通话发起端 502和多个视频通话接收端 506) 初始化失败或与中转服务器 504的连 接中断， 通讯状态设置为指示视频通话发起端 502与中转服务器 504连接正常， 保持 通讯状态设置为指示视频通话接收端 506与中转服务器 504连接正常;判断模块 5044， 与获取模块 5042耦合，设置为根据获取的视频通讯状态判断各个移动终端与中转服务 器 504连接是否正常； 交互模块 5046， 与判断模块 5044耦合， 设置为在视频通话发 起端 502与中转服务器 504连接正常时， 获取视频通话发起端 502的当前视频信息， 并发送给多个视频通话接收端 506中与中转服务器 504连接正常的那些移动终端。 优选的， 交互模块 5046， 还设置为在视频通话发起端 502与中转服务器 504连接 正常时， 获取多个视频通话接收端 506中与中转服务器 504连接正常的移动终端的当 前视频信息， 并发送给视频通话发起端 502。 优选的， 交互模块 5046， 还设置为获取多个视频通话接收端 506中与中转服务器 504 连接正常的移动终端的当前视频信息， 并发送给除该当前视频信息所属的移动终 端外的， 其它与中转服务器 504连接正常的视频通话接收端 506。 优选的， 交互模块 5046， 还设置为将获取的各个移动终端的视频通讯状态发送给 除本移动终端外的， 其它与中转服务器 504连接正常的移动终端。 优选的， 获取模块 5042通过每隔设定时间向各个移动终端发送查询命令， 查询获 取各个移动终端的视频通讯状态。 该查询命令优选的为 SIP的查询命令。 通过本实施例， 有效实现了支持视频通话的多个视频通话移动终端之间的视频交 互。 从以上的描述中， 可以看出， 本发明通过设置中转服务器， 由中转服务器查询判 断参与视频通话的多个移动终端的视频通讯状态， 根据该视频通讯状态进行多个移动 终端之间的视频交互， 解决了现有技术无法实现多个支持视频通话的移动终端同时进 行视频通话的问题， 达到了多个支持视频通话的移动终端同时进行视频通话， 扩展移 动终端的功能业务的效果。 本发明的技术方案优选的， 在 PS (Packet Switched, 分组 交换） 网中实现。 但不限于此， 本领域技术人员可以根据本发明的多个实施例， 将本 发明的技术方案应用于任意适当的通讯网络， 本发明对此不作限制。
